French Indochina Large Silver shops Brooch

Product Name: French Indochina Large Silver shops Brooch
This vintage brooch is unique as well as with its fine detailed filigree work made in French Indochina. Shows vintage wear and tear shops on back, but slide pin is in place and works.  May also be used on a lapel.  It is about 2.5" of eye-catching detail, has a slight dome shape, and weighs almost 20 grams (19.7 g).  It has not been cleaned. Vintage condition, but no flaws. Clasp works fine, tho not perfectly straight. Not sure if it ever was, tho! It is not marked sterling, but has been tested with a commercial x-ray machine for precious metals to be so.(not acid tested for fear of scratching or leaving mark on metal).
